Embodiment 1
[0039] Example 1 Preparation of (R)-3-(4-(2-(2-d3-methyltetrazol-5-yl)pyridin-5-yl)-3-fluorophenyl)-5-hydroxy Methyloxazolidin-2-one phosphate (compound T-1)
[0040]
[0041] Concrete synthetic steps are as follows:
[0042]
[0043] Step 1 Synthesis of 2-(2-d3-methyltetrazol-5-yl)-5-bromopyridine (Compound 2).
[0044] 5-bromo-2-(2H-tetrazol-5-yl)pyridine (0.5g, 2.2mmol) and K 2 CO 3 (0.61g, 4.42mmol) was dissolved in 10mL DMF, and deuterated methyl iodide (0.42g, 2.88mmol) was slowly added dropwise under ice bath. After dropping, the mixture was stirred under ice bath for 1 hour, and TLC detected that the starting material disappeared. Add 40mL of water to the reaction solution, extract with ethyl acetate, wash the organic phase with 20mL of saturated brine, dry over anhydrous sodium sulfate, concentrate, and column chromatography to obtain the oily 2-(2-(methyl-d3)tetrazole -5-yl)-5-bromopyridine (compound 2) 0.27g, yield 52.5%. 1 H NMR (300MHz, CDCl 3 ) 8.8...
Embodiment 2
[0051] Example 2 Preparation of (R)-3-(4-(2-(2-methyltetrazol-5-yl)pyridin-5-yl-3,4,6-d3)-3-fluorobenzene Base) -5-hydroxymethyloxazolidin-2-one phosphate (compound T-2)
[0052]
[0053] Concrete synthetic steps are as follows:
[0054]
[0055] Step 1 Synthesis of 2-(2-methyltetrazol-5-yl)-5-bromopyridine (Compound 6).
[0056] 5-bromo-2-(2H-tetrazol-5-yl)pyridine (0.5g, 2.2mmol) and K 2 CO 3 (0.61g, 4.42mmol) was dissolved in 10mL of DMF, and iodomethane (0.41g, 2.88mmol) was slowly added dropwise under ice-cooling. After dropping, the mixture was stirred under ice bath for 1 hour, and TLC detected that the starting material disappeared. 40mL of water was added to the reaction solution, extracted with ethyl acetate, the organic phase was washed with 20mL of saturated brine, dried over anhydrous sodium sulfate, concentrated, and column chromatography gave 2-(2-methyltetrazol-5-yl )-5-bromopyridine 0.28g, yield 52.7%. 1 HNMR (300MHz, CDCl 3 ) 8.83 (d, J=2.3Hz,...
